Hydro74, aka Joshua Smith, has launched a new line of t-shirts featuring art in his distinctive style that draws on street art and manga – plus work from Jimiyo, Zombie Yeti, and Blue Chicken.

The Brass Tack line’s concept is described as depicting “the simplicity of symbolic imagery meshed with art and intellectual idealism”. Inspired by how the symbols of closed organisations such as the Freemasons are “hidden” in the designs of day-to-day objects, such as money, the shirts include a set of icons and mark subtly hidden throughout the different designs.
